A Coriolis flow meter is a type of flow meter that measures the mass flow rate of a fluid (liquid or gas) by using the Coriolis effect. The Coriolis effect is a phenomenon in which a fluid’s mass flow rate is measured by detecting the twisting force (torque) created by the fluid’s motion.
Coriolis Flow Meter Working Principle.
Here’s how it works:
- The Coriolis flow meter consists of a tube that is vibrated at a specific frequency.
- When a fluid flows through the tube, it creates a twisting force (torque) due to the Coriolis effect.
- The torque is directly proportional to the mass flow rate of the fluid.
- The Coriolis flow meter measures the torque and converts it into a mass flow rate signal.
Coriolis flow meters are highly accurate and reliable, and they offer several advantages, including:
- High accuracy (typically ±0.5% of reading).
- Direct mass flow measurement (no need for density compensation).
- Low maintenance (no moving parts).
- High reliability.
- Wide range of applications (liquids, gases, and slurries).
- Compact design.
Coriolis flow meters are commonly used in various industries, including:
- Chemical processing.
- Oil and gas.
- Power generation.
- Food and beverage.
- Pharmaceutical.
- Aerospace.
Some common applications include:
- Flow measurement in pipelines.
- Custody transfer.
- Process control.
- Inventory management.
- Leak detection.
- Energy management.

What is Coriolis Effect?
The Coriolis flow meter operates on the principle of the Coriolis effect, a phenomenon first described by French scientist Gaspard-Gustave de Coriolis in the 19th century. This effect manifests as a deflection of moving objects, such as fluids, on a rotating frame of reference. In the context of flow measurement, the Coriolis effect causes a fluid flowing through a vibrating tube to exhibit a twisting or bending motion, proportional to its mass flow rate.
